l 16 canin.` (ol. 153-1) The machine of the present invention is designed to set up and apply binding strips to cylind rical containers having a body formed of paperboard, and having metallic reinforcing strips at each end to reinforce the margins'of the body.

In the shipment of ice cream or similar com'- modities in bulk, it is a frequent practice to ship `the same in cylindrical containers intended for 'I'he present invention is designed to facilitatel the expanding of the containers into cylindrical form and to provide means for crimping -the bindy ing strips around the margins of the container, so

20 that after the strips have been thus applied'the container will retain its cylindrical formation and ail'ord a ilrm, strong and rigid receptacle for the intended purpose."

Further objects and details will appear-from a .25 description of the invention in conjunction with the accompanying drawings, wherein,-

Fig. 8 is an enlarged detail, taken on line Il of Fig. l; and

Fig. 9 is a sectional plan view of a portionl of 45 the machine, Itaken on line 9--9 of Fig. 8.

4The machine as a whole comprises a square bed plate I Il, which is supported at a convenient elevation on diverging legs II extending from the corners of the bed plate. On the` front side of 50 the bed plate is an erecting table I2 which is into the cylindrical condition in preparation for the application of the metallic binding strips.

.The Jerecting table is provided on its upper surface with a pair of rollers I4 which are spaced from one another to an extent slightly less than 5 the normal diameter of a split cylindrical mandrel I5, so that when the mandrel is forced between the rollers it will tendv to compress the` same and cause the free edges to overlap in the manner indicatedv in full lines in Fig. 1. 10

Behind the rollers I4 are located positioning blocks I6, each of which is conically rounded on its inner corner I1 to aiford separated stops for contacting the wall of the mandrel and holding it in properly spaced position between the rollers l5 I4. With the mandrel thus compressed, a container wall I8, which is shipped in atwise or folded condition, is spread by hand and slipped upon the mandrel until the margins of the container rests uponthe positioning blocks I6, after which the expanded container with the mandrel within it is removed from the erecting table in preparation forthe application and crimping of the binding strips.

The mandrel, upon being released from the rollers I4 and the'blocks I6, tends to expand within the container and thus bring it to truly cylindrical shape. The mandrel is oi' a less length than the container, so that when it is positioned at one end of the container it will expose a portion of the container wall beyond the mandrel, as indicated in Figs. 3, 4 and 5. Either end of the container may be thus exposed by lshifting the position oi' the mandrel within the cylindrical body of the container.

With the edge of the container thus exposed, a

i binding ring is applied, which ring is preferably of the form shown in the Ronald I. Drake application, Serial No. 5,926, filed February 11, 1935, although the binding ring may be otherwise con- 40 "figured The binding ring, if intended for the top of the container, may be in the form shown mation of the proper width to embrace the edge.-

of the cylindrical container. 'Ihe inner lip is preferably provided with vertically reduced corrugations '25, which not only 'stillen the rim but 55 with` the inner margin of the container wall.

The binding strip shown in Fig. 3 is adapted to embrace not only therim of the container Wall .but also a ange 26 on 'the bottom 21, for which reason the arch 28 is made broader than in Fig. 4, but in other respects the structure is the same. With the strip applied to the margin of the container wall, the wall is supported upon the plate I0 Within the space circumscribed by a series of rollers 29, which as shown in the present instance are six in number, and surround the position occupied by the container and serve to restrict the same during the rotating movements imparted to the container during the process of crimping the binding strip thereon. As shown, the rollers are spaced away from the position normally occupied by the container so as to allow considerable freedom of movement thereto, but inthe event the whipping or sidewise movement of the container becomes excessive, the rollers afford anti-friction contact points for preventing undue movement.

The crimping is eiected by a crimping roller 30 which is mognted upon a vertical shaft 3| and held in place by a washer 32 and screw 33. The upper portion of the roller 30 is beveled, while f the lower portion 34 is cylindrical and serrated to aiord a biting grip against the inner lip of the binding strip. The shaft 3| is journaled within an annular flange 35, and the shaft carries a bevel pinion 36 which is secured to the shaft by -a pin 31. The lower end of the shaft is carried within a thrust bearing 38, and the pinion 36 meshes with a driving pinion 39 carried by a transmission shaft 40, which through suitable reduction gearing 4| is entrained with a motor shaft 42 driven by a motor 43 carried by the frame of the machine.

The Avbevel pinion 36 is provided with an upwardly extending pin 44 which is adapted to coact- Fig. 8, but is adjustable to the position indicated in dotted lines to coact with the pin in a manner presently to be described.

` The star Wheel with the associated cam is carried by an adjustable pintle 49 having a head 50' which is entered through a plate 5| secured by screws 52 to the top of the cam. The pintle 49 is slidable within a bushing 53 rigidly held within a sleeve 54 depending from the frame of the machine (see Fig. 8). The bushing 53 is provided with a counter bore 55 which receives a coil spring 56 bearing against a head 51 at the lower end of the pintle, which head is contacted by a hardened boss 58,011 the end of an arm 59 xtending inwardly from' a journal head 60 carri d by a fixed pivot pin 6| outwardly pro' the bottom of the machine (see Fig. 8. I'he idle roll is thrown into crimping position by the action of a draw rod 65, one end of which is pivoted to the arm 62 and the opposite end of which is entered through a boss 66 on the vertical arm 61 of a bell crank lever 68. the

The star wheel is normally lifted above the upper end of the pin 44 as indicated in full lines in horizontal arm 69 of which has pivoted thereto the upper end of a treadle rod 10, the lower end of which is pivoted to a treadle arm 1| pivoted at its rear end to one of the legs of the frame, and provided at its forward end with a foot treadle 12.

I'he draw rod 65 beyond the lug 66 is encircled by a coil spring 13 which bears against a nut 14 on the end of the draw rod, the spring aording a cushion for imparting movement from the' bell crank to the draw rod. The upper end of the bell crank arm 61 ls entered within a recess 15 on the under side of a slide bar 16 and is held in position within said recess by contact with hardened cross pins 11. The slide bar 16 at its inner end carries a-rol1er 18 which bears against the cam 41.

Operation In operation, with the foot treadle elevated by the tension of a spring 19, the parts will occupy the position shown in full lines in Fig. 6, with the compression roll retracted from the crimping roll to aiford an easy entrance for the rim of the container with the binding strip applied thereto. Such entrance is facilitated by the beveling of the upper surface of the crimping roll. After the edge of the container wall has been positioned, the operator depresses the foot treadle 12, which draws down the bell crank into the position shown in dotted lines, and this in turn imparts a pull to the draw rod 65, which serves to swing the arm 62 inwardly through the medium of the cushioning spring 13, which action draws the compression roll 64 into compressive relation with respect to the crimping roll.

The crimping roll is constantly rotating through the train of connections with the motor, and, as soon as pressure is established, the serrated crimping roll will not only tightly crimp the binding strip against the rim of the container, but will also cause the container to rotate, thus progressively bringing every portion of the binding strip into the bite of the rolls.

by the downward movement of the arm 59 which allows the pintle 49 to move downwardly under the pressure of the coil spring 56.

The movement of the foot treadle also draws 'back the slide bar 16 through the action of the bell crank lever arm 61, which retracts the roller 18 from the depression 48-in the cam 41, so that after the star wheel has been initially moved byA the engagement of the pin 44, the elevated portion ofthe cam will be presented to the roller 18, which permitsv the operator to remove his foot from theV foot treadle and serves t o retain the parts in operating relationship, since the return movement of the foot treadle will be prevented by the engagement of the roller with the cam.

The operation thus initiated will' continue until the star wheel, by intermittent movements, has completed a cycle of rotation, which again brings the cam depression into registry with the slide plate roller and permits the 'restoration of the parts to inactive position, thus terminatingthe v crimping operation. After o'ne end of the cona similar operation. o

The mechanism is one which permits the expanding of the containers to be easily, uniformly and rapidly performed by the operator, and per- 'mits the 'crimping to proceed after being once initiated, so that the operator, during the performance of the crimping operation on one of the containers, may center his attention on the expanding of the next container in preparation for the crimping operation, it being desirable to employ duplicate mandrels, so that, while one of the mandrels is employed in the crimping operation, the other may be utilized in preparing the next succeeding container. i t
